Software Engineer, Growth

Who we are:

Our name is inspired by Theodore Roosevelt’s ‘Citizenship in a Republic’ speech, which pays homage to the ‘(hu)man in the Arena’. To us, entering the Arena means committing oneself fully and accepting the risk of failure in the pursuit of an audacious, worthy cause.

We’re a close-knit tribe of scientists and builders exploring the boundaries of how artificial intelligence can benefit humanity. If you share our passion for delving deep into real-world problems and solving them with fully autonomous AI, join us in the Arena.

What we do:

Arena empowers businesses across industries to make high frequency, critical path decisions fully autonomous. Our products have helped some of the world’s largest CPG, manufacturing, and electronic companies transform their sales and supply chains into increasingly autonomous, self-learning systems — unlocking efficiencies and resulting in better, more affordable consumer experiences. 

Arena knows that autonomy can help organizations tackle much more, from delivering critical goods and services more affordably, sustainably, and equitably to the world, to reducing green premiums on renewable energy to compete more effectively with fossil fuels.

About the role:

Our engineering team works directly with customers to solve complex, mission-critical challenges using Arena’s cutting-edge products and technologies. Engineers own the full solution lifecycle—from problem identification, designing and implementing data-driven solutions, to demonstrating their value in real-world scenarios.

As a Software Engineer, Growth, you'll operate like a startup CTO. You’ll work closely with both customers and Arena teams to build end-to-end systems in small, agile teams, working on fast timelines. Your responsibilities will include designing systems, analyzing large datasets, developing tailored applications on top of Arena’s product stack, interacting with users, and training AI models.
By addressing specific customer challenges, you will play a pivotal role in refining and scaling Arena’s products, contributing to their broader adoption and success.

This is a unique opportunity to gain hands-on experience in driving innovation across some of the world's most vital industries, making it ideal for those aspiring to become entrepreneurs or future engineering leaders.

How you will contribute:

• Prototype moonshot ideas and push the boundaries on what is possible. 
• Spearhead the development of the next generation of machine learning software with a focus on Core Intelligence (ML Modeling), Telemetry (Impact & Algorithmic Health), and AI interfaces.
• Drive the development of new features or custom applications by either extending Arena's products or creating tailored solutions.
• Travel both domestically and internationally up to 50% of your time.
• When not traveling, you will work in-person at Arena's NYC headquarters.

You Have:

• 1+ year of professional experience post-graduation in software engineering or a related field.
• Demonstrated enthusiasm and knowledge of Artificial Intelligence and Machine Learning concepts.
• Proven ability to write clean, efficient code.
• Instinct to break down complex problems into small building blocks.
• Strong communication skills with empathy for end-users, ensuring usability across UI, API, and SDKs

Benefits & Perks Include:

• 99% of the monthly premium for Aetna medical insurance, plus vision and dental coverage
• 401(k) Retirement Plan
• Unlimited PTO
• Lunch every day from local restaurants via Sharebite
